To all whom it may concern: g 1

7 Be it known that I. CARL W. BUGKLER, a citizen of the United States,residing at-Lexington, in thecounty of Fayette and State of Kentucky, have inventedvcertain new and useful Improvements in Fireplace-Heaters,

' of which the following is a specification,

' The purpose of my invention isto provide a fireplace heater having high efiiciency as a heat conserving device, and; which may be manufactured and installed at relatively small cost. The heater comprises a hollow metal body, preferably cast in one piece,*and having a base which underlies the grate, and a back piece having a forward wall which overlies the grate, whereby the air which circulates through the heater will be heated by the flames and hot gases passing upwardly from the grate in contact with the back portion and by the hea-tradiated downwardly from the grate on to the base portion. The back piece is provided with an air inlet in its upper portion, through which external air may be admitted tothe heater,

and the base is provided with an outlet opening near its forward edge through which the heated air may pass out of the heater into a suitable conduit and thence through a register into the room. The draft in thechimney causes fresh air to be drawn continuously into the heater and thence through the register into the room in which the heater is located. 7 In the accompanying drawing, Fig. l is a central vertical section through a heater made in accordance with my invention, showing the same arranged in a fire-' place and connected to a register in a room; and,

Fig. 2 is a perspective view of the heater,

with a grate support attached, the latter being partly broken away.

Referring to the drawing, (4 represents the heater, and 7) represents a grate support which may be of any desired form and may be secured to the heater body or separately 7 V supported'on its base. The heater comp-rises a hollow metal body, preferably cast'in one piece, and consisting of a hollow base 1, relatively fiat and of such length, width and contour as to fit snugly within the walls of the fireplace at the bottom ofthe latter. A hollow back piece 2 projects upwardly from the rear of the base piece and fits against the rear wall 3 of-the fireplace, this back piece being of the same length,from side to side,as the base piece and adapted to fit against the side walls of the fireplace; The. rear wall 2 of theback piece is :flat andlies against the wall 3 of the fireplace, whilethe forward wall of the back piece has a part 2 which extends upward: from the base piece and substan:

tially parallehwith the'wall 2 to a point slightly above the grate 4,;and a part2 which inclines forwardly and upwardly fromthe part2 and overhangs the grate and thebase piece.

The base piece has an air e outlet 5 at its forward edge, preferably projecting downwardly, as shown, and the back piece-has an air inlet 6 in its upper part, this inlet, as shown, being in the form of a short tube which, when the heater is in position,

projects through an opening in the rear-wall of the fireplace to admit fresh air into theheater. The heater proper'may be cast with or without the grate support b. Any suit-t able form of grate supporting means there:

. for may be provided and the support'may be secured to the heater body-or may rest upon the base of the heater. Preferably, the ho-l-' low back piece is PI'OVldGdl with internal baffles 9, projecting from its front and rear walls, to cause the air to take a longer course through the heater in contact with the heated metal; but thesebafiles may beomitted, if

desired. 7

The device is installed by placing it in the fireplace, as shown, and connecting tov the outlet 5 a pipe 7 which is carried beneath the floor to a'yregister 8, which may be inserted in the floor or arranged in the room at any convenient point remote from the heater.

In operation, the doors and windows being closed, the draft up the chimney will cause air to be drawn through theheater' and register into the room, and this heated air replaces the air passing up the chimney. It is to be noted that the air receives heat from the fuel in the firebox throughout course through the heater, since the part'of the heater above the grate is in direct contact with the flames andhot gases,'and the part small, and because of the'large heating sur-' face to which the air is exposed in its p'assage through the heater, the later is very hat I-e1aiin is': v 7 r V 1.
